mkvmerge: bug fix: MP2/MP3 audio tracks in MPEG program streams that contained garbage at the start of the very first packet caused mkvmerge to use uninitialized/random values for certain parameters (sample rate, number of channels, and therefore also during timecode calculation).

mkvmerge: new feature: mkvmerge will remove stuffing bytes from MPEG-1/-2 video streams that are used to keep the bit rate above certain levels (the 0 bytes between slices and the following start code). Implements #734.

all: bug fix: The programs do not try to create directories with empty names anymore. This happened if the output file name for e.g. mkvmerge or mkvextract was only a file name without a directory component. With Boost v1.50.0 the call to "boost::filesystem::create_directory()" would result in an error if the name was empty (it didn’t in earlier versions of Boost).

mmg: bug fix: Fixed mmg not reading the very last line of mkvmerge’s output. The result was that messages like "the cues are being written" did not show up in mmg and that the progress bar was not filled completely. Fixes #774.
